Abstract
The utility model discloses a rigid polyurethane foam composite board embedded with inorganic foam. The rigid polyurethane foam composite board is characterized by comprising a core inorganic foam board (1), a rigid polyurethane foam layer (2) and flame-retardant cement base interface felts (3). The rigid polyurethane foam layer (2) is coated on the core inorganic foam board (1), and the flame-retardant cement base interface felts (3) are adhesive to an upper surface and a lower surface of the rigid polyurethane foam layer (2). The rigid polyurethane foam layer (2) is coated on six sides of the inorganic foam board, so that surface pores of inorganic foam materials are improved, water absorption of an inorganic foam surface is reduced, and toughness of the inorganic foam materials is increased; by the adoption of the flame-retardant cement base interface felts (3), the composite board is completely adaptable to a construction technology of thin plastering external insulation; and instruction of the inorganic materials improves combustion performance grading of the materials, and the composite board can be used for fire-proof barriers.
Description
Technical field:
The utility model relates to the building thermal insulation material technical field, is a kind of embedded inorganic foamed type rigid foam polyurethane specifically, can be used for the fire barrier of the outer insulation of external wall.
Background technology:
Froth inorganic stock refers to the cellular insulant be made up of inorganic matter; Inorganic cellular insulant mainly contains foam glass, foam concrete (cement), foamed ceramics etc. at present.Foam glass is to be primary raw material with quartz sand, cullet, adds blowing agent and auxiliary agent, through grind, foaming, annealing, cutting and a kind of heat insulating material of making; The foaming cement thermal insulation plate is main gel rubber material with Portland cement, by the chemical blowing method, is that main inorganic material is made into lightweight, high-strength, insulation and the good heat insulating material of fireproof performance with cement; Foamed ceramics is the porous ceramic bodies with high porosity of three dimensions space truss structure, and it has, and porosity height, specific area are big, high temperature resistant, resistance to chemical attack and excellent mechanical intensity and filtration absorption property.The maximum characteristics of inorganic cellular insulant are: the incombustible material of combustibility A level; Safety and environmental protection; Life-span is long; Reusable edible etc.; The shortcoming of froth inorganic stock is, material is loose frangible, should not construct, and rate of closed hole is low, and waterproof and heat-insulating property are lower than organic insulation material.
The hard-foam polyurethane heat insulating material comprises polyurethane rigid foam plastic (PUR) and polysiocyanurate rigid foams material (PIR); Hard-foam polyurethane is present best organic insulation material, and the shortcoming of hard-foam polyurethane heat insulating material maximum is that combustibility does not reach the A level and do not fire, heat release and discharge poison gas in flame easily.
Summary of the invention:
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and provide a kind of embedded inorganic foamed type rigid foam polyurethane, problem such as solve mainly that inorganic foamed warming plate rate of closed hole is low, water resistance is poor, material is loose, anchoring is frangible, coefficient of thermal conductivity is high, heat-insulating property is relatively poor and hard-foam polyurethane heat insulating material burning grade is low.
The technical solution of the utility model is: embedded inorganic foamed type rigid foam polyurethane, its special character are that it is made up of the inorganic foamed plate of core, hard-foam polyurethane layer and fire-retardant cement based interface felt; Described hard-foam polyurethane layer coats the inorganic foamed plate of core, and the upper and lower surface of hard-foam polyurethane layer is pasted fire-retardant cement based interface felt.
Further, described inorganic foamed plate thickness is not less than 15 millimeters.
Further, the inorganic foamed plate of described core can be a kind of in foam glass, foamed ceramics or the foam concrete (cement); Described hard-foam polyurethane layer is to comprise a kind of in polyurethane rigid foam plastic (PUR) or the polysiocyanurate rigid foams material (PIR).
Compared with the prior art embedded inorganic foamed type rigid foam polyurethane described in the utility model has following good effect, and 1, this composite plate has good fire retardant performance, can be used for the outer insulated fire isolation strip of external wall; 2, because hard-foam polyurethane also has very outstanding heat-insulating property (coefficient of thermal conductivity is less than 0.024W/ (m.K)), behind its coated inorganic foam heat-insulating board, can effectively reduce system's coefficient of thermal conductivity of composite plate, improve the heat-insulating property of composite plate; 3, because inorganic foamed warming plate surface is coated sealing by hard-foam polyurethane, improved inorganic foamed water resistance and the cracking resistance of core; 4, because embedded inorganic foamed type rigid foam polyurethane has used fire-retardant cement based interface mat as the composite surface material, composite plate can be used for external insulating system for thinly plastered external wall (being specially adapted to the position, fire barrier); 5, composite board product can with the same life-span of External Thermal Insulation System, have good application life and workability.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
In order to understand better and to implement, describe the utility model in detail below in conjunction with accompanying drawing.
Embodiment 1, and referring to Fig. 1, the inorganic foamed plate 1 of core is selected the thick foamed cement plate of 40mm for use; When with the polyurethane high pressure foaming machine the inorganic foamed plate 1 of hard-foam polyurethane layer 2 foaming coating core being the foamed cement plate, fire-retardant cement based interface felt 3 is compound to hard-foam polyurethane layer 2 two sides, the rate of closed hole of hard-foam polyurethane layer 2 is greater than 90%, and the level pressure typing makes embedded inorganic foamed type rigid foam polyurethane.
Embedded inorganic foamed type rigid foam polyurethane described in the utility model, use hard-foam polyurethane layer coated inorganic cystosepiment surface, improve rate of closed hole, the water proofing property of froth inorganic stock, pliability, for satisfying thin plastering construction technology, paste fire-retardant cement based interface felt in hard-foam polyurethane layer upper and lower surface, make composite plate and building mortar that advantages of good caking property be arranged, also be difficult for fragmentation when using anchoring piece to penetrate composite plate, have good heat preservation and soundproof performance and good fire protection flame retarding simultaneously.
